Working machine, trouble diagnosis system of working machine, and maintenance system of working machine

A working machine failure diagnosis method for performing a failure diagnosis by transmitting and receiving signals through communication devices provided at a working machine and at an information management center comprising:

• a first step in which a first signal related to a failure of the working machine is generated at the working machine and the first signal is transmitted to the information management center from the working machine via the communication devices;
• a second step in which, after the first signal is transmitted, the information management center generates a second signal for identifying a location of the failure based upon the first signal and the second signal is then transmitted from the information management center to the working machine via the communication devices;
• a third step in which failure information corresponding to the first signal and the second signal is provided to an operator;
• a fourth step in which a signal related to a service request for the identified failure location is transmitted from the working machine to the information management center;
• and
• a fifth step in which a servicing cost and a length of servicing time are calculated at the information management center based upon the signal related to the service request and information indicating the cost and the length of time is transmitted to the working machine.
